JavaScript array sort alphabetically

We can sort the JavaScript array elements by using the
sort() method of Array class in JavaScript. Syntax of the sort method is as
given below:

arrayObject.sort(SortFunctionName)

"SortFunctionName" is optional in the
sort method but when it will be passed then it should be a function. Here in our
example of sorting the array elements we have used simply the sort() method
since by default it sorts array elements alphabetically. After using the sort()
method array will change. In this example we have used an array of five
elements which all are strings. Here you can see that how the sort()
method can be applied on the array to sort their elements alphabetically.
